Summary
There are plenty of memoizing libraries on Hackage, but they usually fall into two categories: * Store cache as a flat array, enabling us to obtain cached values in O(1) time, which is nice. The drawback is that one must specify the size of the array beforehand, limiting an interval of inputs, and actually allocate it at once. * Store cache as a lazy binary tree. Thanks to laziness, one can freely use the full range of inputs. The drawback is that obtaining values from a tree takes logarithmic time and is unfriendly to CPU cache, which kinda defeats the purpose. This package intends to tackle both issues, providing a data type 'Chimera' for lazy infinite compact streams with cache-friendly O(1) indexing. Additional features include: * memoization of recursive functions and recurrent sequences, * memoization of functions of several, possibly signed arguments, * efficient memoization of boolean predicates.

General
- doc
- Add extra documentation (API, Javadoc, etc). It is recommended to enable per package instead of globally
- hscolour
- Include coloured haskell sources to generated documentation (dev-haskell/hscolour)
- profile
- Add support for software performance analysis (will likely vary from ebuild to ebuild)
- representable
- Define Representable instance from adjunctions package
- test
- Enable dependencies and/or preparations necessary to run tests (usually controlled by FEATURES=test but can be toggled independently)
